AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

A company has an on-premises data center connected to AWS through a Site-to-Site VPN. Applications on-prem must resolve the private Route 53 records of a VPC-based domain (corp.internal). Which configuration will enable name resolution without exposing the VPC to the internet?

  • Create a Route 53 Resolver outbound endpoint in the VPC and add a forwarding rule sending corp.internal queries to the on-premises DNS server.

  • Create a Route 53 Resolver inbound endpoint in the VPC and configure the on-premises DNS server with a conditional forwarder for corp.internal that points to the endpoint's IP addresses.

  • Associate the private hosted zone with the default VPC and update the VPC DHCP options set to use AmazonProvidedDNS.

  • Deploy an Interface VPC Endpoint for Route 53 and allow inbound TCP/UDP 53 from the data center.
